I saw a clip about Jill Bolte on the CBC the other night — totally fascinating. She relates her amazing experience of having a stroke from a brain researchers point of view.
The part about loosing the function of her left-brain function was really interesting. In her right-brain she had no concept of language, time, or numbers — she felt like she lost the boundries of herself and describes a state of consciousness similar to nirvana.
I’ve had heard of similar experiences resulting from LSD.
